THREAD-TlER.

SPECIFICATION forming part of Letters Patent No. 5,571, dated August '7, 1900.

Application filed September 20,1899. Serial No. 781,090. [No model.)

To all whom it may concern:

Be it known that I, JAMES WILLIAMS Mc-.

CARTHY, of Ware, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Thread-Tiers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in thread-tiers by which the ends of two threads or yarns after being knotted together will be of uniform lengths. v

The primary object of the invention is to provide a simple device of 'this character.

which will be separate from and independent of all supports or mechanisms of any kind, so that its two ends will be free, in order that threads may in the formation of a knot be passed around the device and across both of its ends.

A further object is to provide a device which may be conveniently carried in the pocket of the operator.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective. Fig. 2 is a side elevation. Fig. 3 is a central longitudinal sectional view. Fig. 4 is a transverse sectional view on line 4 4, Fig. 2. Figs. 5, 6, 7, 8, 9, 10, and 11 show the various steps in the formation of a knot.

Referring to the drawings, A designates a plate the upper end of which is beveled. This plate is formed with a slot a, dividing the upper portion of the plate into arms 1 and 2. The plate is in practice held in front or toward the operator. The back or rear plate 13 is formed with a central tongue 3, which is bent inwardly at 4 and at its upper end is carried a short distance beyond the ends of arms 1 2. This tongue is in line with the slot a, into which it enters when the two plates are pressed together. The plates A and B are shown as being made from one piece of metal, with a bowed portion 5 connecting them together to form a spring the office of which is to normally hold the tongue 3 out of but in line with the slot 0. It is obvious, however, that the two plates may be otherwise connected and held in normal relation to each other. The edges of the tongue and the opposed edges of the two arms are beveled, as at 6. tion of a knot brought between the arm 2 and the adjacent edge of tongue 3 and are firmly held by the twoplates being pressed together. They are broken off close up to the arm when a pull is exerted upon them. The arm 1 acts as a brace or stop for the tongue, preventing it from slipping away from arm 2 when the threadsare being broken. It will be noted that the bevels of the tongue conform to those of the arms 1 and 2, so that when the plates are pressed together the tongue 3 is not free 'to move away from arm 2 when the pull is exerted on the threadsto effect the breaking thereof.

This device may be carried in the pocket of the operator or attendant upon a textile machine of any character where the ends of yarns or threads are required to be tied together. It is well known that in order to prevent subsequent annoyances the ends of the threads or yarns after the knot is made must be short and of uniform lengths. The threads or yarns to be tied are usually those of two spools or bobbins, the winding being from oneto the other.

In practice the device is held by the thumb, index, and second fingers of the left hand of the operator, as indicated in dotted lines, Fig. 1. The two threads to be united are brought together over the thumb and back of the device, above the index finger, and then to the front, (see Fig. 5,) then again to the back beneath the second finger, (see Fig. 6,) and to the front up beneath the thumb, (see Fig. 7,) and then inserted between the tongue and the arm 2. (See Fig. 8.) The two plates are then pressed together, binding the threads between the tongue and the arm 2. By pulling on the ends of the threads they will be both broken tight up against the arm; (See- Fig. 9.) The two loops now back of the device are slipped over the upper ends'thereof, and the threads are then taken by the fingers of the right hand and pulled into a tight knot close to the front surface of plate A, whereupon pressure is removed from the plates and The threads are in the formathe short ends of the threads are released by the tongue. These ends are then of uniform lengths.

The advantages of my invention are apparent to those skilled in the art to which it appertains.

I claim as my invention 1. As an article of manufacture, a threadtying device composed of a single piece of metal bent to form two plates, one of said plates having arms, and the other a tongue capable of binding against said arms, said plates being designed to be held between the fingers of one hand of the operator and pressed together to hold threads between the tongue and arms, as set forth.

2. A thread-tyin g device composed of a single piece of metalbentback over itself to form two plates, one having an arm and a stop, with a space between them, and the other a tongue capable of binding against such arm and stop, as set forth.

3. A thread-tying device composed of two spring-held plates, one having an arm and a stop formed with beveled edges, and the other a tongue beveled to conform to such edges, of the arm and stop, as set forth.

4. A thread-tying device composed of two spring-held plates, one having two parallel arms formed with beveled edges,and the other a tongue beveled to conform to the edges of said arms, as set forth.

5. A thread-tying device composed of two plates and a spring for normally holding said plates out of contact with each other, one of said plates having two arms with an intervening slot, the other plate having a tongue capable of tittin g within said slot, the threads to be knotted being designed to be passed around said plates and across both ends thereof and between the tongue and one of said arms, as set forth.

6. A thread-tying device composed of two plates, and a bowed spring uniting said plates at one end, one of said plates having two arms with an intervening slot, the other plate having a tongue capable of fitting within said slot, the threads to be knotted being designed to be passed around said plates, across the upper ends thereof and also across said spring, and between the tongue and one of said arms, substantially as set forth.

In testimony whereof I have signed this specificationin the presence of two subscrib ing witnesses.
